I frequently observe the following exception messages on the startiot page:

I’m trying to figure out of this is a problem on my end or on the startiot page. The elastic search errors read something like “[es_rejected_execution_exception] rejected execution of org.elasticsearch.transport.TransportService”. A bit of google-fu suggests that this (and the search_phase_execution_exception) means the bulk operations queue might be full? Something to do with ElasticSearch I guess. I don’t entirely understand what the problem (or solution) is, but I hope it can be resolved.

That illegal argument exception pops up occasionally, but not as often as the elasticsearch errors. It isn’t really repeatable or consistent either, i.e. it sometimes shows up but for different variables defined in the uplink transform.
